I've been baking this out of tree for long enough. This is currently about ~2/5ths the size of TRPL. Time to get it in tree so it can be more widely maintained and scrutinized. I've preserved the whole gruesome history including various rewrites. I can definitely squash these a fair amount if desired. Some random people submitted minor fixes though, so they're mixed in.
Edit: forgot to link to rendered http://cglab.ca/~abeinges/blah/turpl/_book/
Edit2:
To streamline the review process, I'm going to break this into sections that need official "domain expert" approval:
